" had to tbedrawiugs accompanying and forniing a part of the same.

My invent-ion isan improvement in that class of breech-loading tirearms known as magazine-guns; and the object of the same is to produce a gun more rapid and certain in its action, stronger in those mechanisms which in arms of this character are commonly of a complicated and delicate character, and *"c'ontaining fewer parts than those heretofore made, and capable of thc same'action Urresult" The general principle of the manipulation or operation oi' my improved fire-arm is simi- -lar in certain respects to that of others now in use-that is to say, 'the cartridges to a certain number are placed in a cylindrical magazine under and along the barrel. In this they are subjected to springpressure, which forces vthem backward toward the breech, while the operations ot'loading,ejecting the empty shells, and reloading are effected by the movement of .a pivoted lever, which serves as the trigger ,giiard. My improvements are chiefly in the breech mechanism operated by this lever, and

through the instrumentality of which the several operations named are performed.

Heretot'ore magazine-guns have been devised in which the breech-block as capable of a vertical movement, or one at right angles to the breech, and various devices have been proposed for imparting to such breeclrblock an intermittent movement by a continuous movement ot the operating-lever or triggerguard. The main advantage of this t'orm of gun is that it dispenses with the usual bolt for forcing the cartridges in the ehamberand sustaining the explosion. ln addition to this I have secured by devices of novel and improved construction other advantages, which will be set forth in the subsequent description of the features that constitute my invent-ion.

The gun which l have devised, and which .contains the improvements which form the subject of this application, is constructed in the following generalmanner: It has a barrel The hammer and trigger are of 6o slides the breech-block, which is practically l solid. .At the rear of the breechblock 'are stout guides, forming part of the case itself,

land which rest-rictthe movement of the block "to a path at right auglesto thebarrel; Inoue` side of the breech-block is a slot of irregularA shape, in which enters a piu carried by anT arm rigidly connected'to the roeklshafttop# erated bythe trigger guard or' lever. On'f'the y opposite'side of the breech-block vis .anzarm pivoted 'to the side of the breech case and connected with the aforesaid rock-shaft by a lever that imparts to it an oscillating movement corresponding to the Vmovement of the triggerguard. This armeztends upward alongside the breech-block, and is then connected with the extractor and injector. These parts are so constructed and combined that a forward-and downward .movement of the trigger-guard produces a downward movement of the breeclrblcsff; het, as soon as this has cleared the breech the piu carried by the actuating-arm enters a portion of the slot, in

which it ceases for a time toimpart any movement to the block. While this is taking place the extractor is operatetkand thrown pack- Award sufficiently 'to partially or wholly withdraw a cartridge or shell from the chamber. The brcech'hlock is then encountered again by the pin moving through the slot in its side, and moved farther downward untill-it passes below the opening of the magazine.' Here it takes up a cartridge, and by the, reverse movement of the trigger-guard the cartridge isA raised to a level with't-he breech, anduthcn. while the breech-block remains stationary, it is forced into the chamber, which is immediately closed. These-the principal features in the cycle of operation, are attended by cerf 'tain others which contribute to the more suc` cessful action of the arm, and which are brought about by certain details which will be hereinafter described.

Having thus generally described the nature charge. Fig. 3 is a View of the gun with Athe breeeh-case` in sect-ion, to exhibit the breech mechanism as it appears at the time when the breech-block has been carried .just below the breech or -chamber and the extractor is about to be brought into operation. Fig. 4 isa simi lar view showing the opposite side of the breech mechanism. Fig. 5 exhibits the parts in their relative positions at the time when the extractor has been thrown back ward to its fullest extent. Fig- 6 shows the mechanism at thetime when the brecclrblock has reached its limit of downward movement and received a fresh cartridge t'roin the magazine. Fig. 7 is a horizontal section ou line x xofFig. 6. Fig. 8 shows the gun in coudition for tiring a sccond time. Fig. 9 is a detail ofthe explodingpin.

The letter A designates the barrel, A the magazine, -B the stock, and B the breeehlilease, of the gun. In one or both sides of the latter are openingsa, which are closed by close-fit ting plates, and which aiiord access to the interior of the case for purposes oi' examination or repairs. The barrel is screwed or other wise firmly united tothe breech-case B, and

the magazineis similarly secured, both cntcr ing the forward end ol' the case and ending flush with its inner wall. The breech-case is extended in tubular form and secured to the stock in any convenient manner. y

C is the hammer, carried by a pin, n', that passes through the sides of the rear portion ot' the breech-case. r1`he hammer is actuated by a spring, b', and. sprung by a trigger, c, in the usual manner. 1

D is thebrecclrrblock, which is oifhard metal and practically solid. actuated tiring-pin, c', (shown in Fig. il.) and in its upper l'acc contains aehanncl orgroovc, in which the cartridge lics.

[n oi'derthatthc hrccclrblock may not move too freely oi' independently by its o wn weight, iu the casing, it hasl attachcd toit a spring,f1, that presses against the side ftfthc casing. The purpose of this will subsequently more fully appear. 'lhe brccchblock cxtcnds from the front to the rear oi' thc chamber foi-mcd tor it in the breech-case l5, and is restricted by those sides to a'vertical movcmcnt. lt docs not,

5 however, occupy allot' this chamber, spaces being lci't on each side oi' itl lor thc arms or levers that control its movement and operate lt contains a spring' the extractor. The construction in this parg ticular, however. may bc somewhatmodified, as recesses (or thc last-named instru mentalities may bc provided iii the sides ot' thc case B. E is the trigger-guard. It is pivoted to the forward and lower part of the breech-case. and, so far as the principle of this invention is concerned, its manner of connection maybe greatly varied. In the present case it is cari ried by aspiudleor rockshaft. E', to which ity mparts a partial revolution when it is turned. )its normal position is shown in Figs. land 2. in which it is held against the stock by a spring-catch, e. A curved arm, F, is carried -hy the axle or spindle of the hammer, and is connected to the lever E by a link. F. Below the fulcrum of the hammer is a pin, c, that, extends into the path ol the arm F, so .that when the ievcr l'] is depressed the arm F is drawn forward and the gun cocked. ln one side ofthe. breech-block l) is a slot, f, with double canraccs. The general directi'on of the slot` is at rightl angles to the liueoi' movement to thc brcech-bltmk; but the rear portion is lower or nearer the bottoni of the block, and is connected with the higher and forward portion by a nearlyvcrt-ical part. Au arm, G, is rigidly secured tothcrockshail ll, and at its end carries a pin. y. that enters the slot f. The tendency of this arm is to lower the breech-block when the lever Eis depressed i bythe Contact ot" the, pin g with the lower cam-face of t-hc slot, and to raise the breechblock when the lever E is raised by the pressure oi' the pin y upon the` upper camface of the slot. When thc breech-block is in its highest position thc pin .f1 is in thtI forward cnd ot" the slot. liy depressing the lcvcr l), it is moved backward along; tlieslot :ind the brccchblocl.' is -drawn downward. Alter a certain backward movement ofthe pin g, however.' it .enters the vertical portion ot' thc slot f; but here, as it. encounters i'or a cci-tain part ol' its path no part, vol' thc bijcecli-l'iloclt', the laltcr remains stationary. As soon as thc piu i'cachcs thc lower l'acc oi' thc lower and i'cai portion ol thc'slot fr however, thc breechblock is again sct in movement and carricd to its lowest' position. rl`hc converse ot' this takes place when thc lcvcr 11 is rais-cd. 'l`hus ofthe lcvci` li bctwccn ils limits of movement is continuous, thc breech-block which is controlled by it. stops for :i time in its path. Un thc opposite side oi' thc bi'eccirblocl( is :in arm, ll, on a stud, h, secured to thc sidcot thc breech-case l5. lhc cnd ol' this arm is bii'uri cated and engages with a pin,/i',sct in :i block, that is cariicd in a guido, la. 'l`o thisblock if is sccurcd a springczitcn, i', which scrvosas thc extractor and in icctor. A second arm.l[, is pivotcd on a stud, 1.", set in thc sido of the l brooch-case, and the end oi' this arnnwhch is i bii'ni'catcd,cn;ag!i willi a pin, l, sct .t short distance l'roni thc l'nlci'uni ol` thc lcvci.' il. 'lhe arm ll' maybe carried by thc roclcshat't Il'; but with the double purpose ol' cconomiziin,r

it. will be seen that although thtl movcmcnt Ais recess, p,gig the breech. Y

time when"alic'artridge is received by thel space and imparting a sudden movement to the extractor, the following means of operating the arm H by the rock-shaft Ei are employed. The arm H above the fulcrum is cut away, leaving two points, n n. The arm is so placed that the rock-shaft E lies in the cut away portion. Over the arm H' is a hub, o, on the rockshaft, one half of which is cut away; or'two lugs on opposite sides of the shaft would serve the same purpose. A stout spring, o', secured to the breech-case, bears upon the end of arm H', just below the point An. Now, when the lever E is depressed and the rock-shaft 3 turned the rear edge of the hub o, or the lug which may be used in its stead. encounters the point vn and turns the arm H downward. This imparts a movement to the lever or arm H. and draws the extract or away from the breech. After a short downward movement the spring 0 cornes into play and forces the arm H by a sudden movement through the remainder of its path,and brings the point n up against the forward 'edge of the hub 0. When the lever E is raised again, the arm I-I is therefore forced positively upwa d by the pressure of the hub upon the 'point u.

`There is a slight play between the hub and y the `points n n', so that the lever E is moved through a certain space without imparting movement to the arm H and the extractor.`

The extractor slides on the guides k up into a Its positiomat the breechblock and presented to the breech, is shownrin Fig. 7. In its forward movement the springe-.itch z" engages with the rim of the shell and forces or draws the cartridge into the breech-chamber. When the cartridge is thus' driven home,the springcatch z" slips over the rim of the shell and into the recess p and alongsideof the cartridge. When the lever E is again depressed, the spring-catch,engaging with the opposite side ot the cartridgerim, forces the same out of the chamber.

In order that the cartridge or the empty shell may be held in engagement with the spring-catchi, a plate or arm,1, is hinged in a recess, o", in the breech-case opposite to thc catch i and near the top of the breech block. Combined with this plate is a spring, s, that causes the plateto swing outward into the space labove the breech-block when the latter is lowered. Vv'hen thc breech-block is up` it forces this plate into the recess 7"; but assoon as the breech-block is lowered the plateis f'orced out into the space above it', and its edge forms a guide for the cartridge.

The operation of the gun in detail is as follows: A suitable number of loaded shells are introduced into the magazine by dropping the breech-block and inserting the shells through the breech-case, and the gun brought into condition for tiring by raising the leverE.

This draws down the breeelrblock, as hereinafter explained. When the breech-block has passed below the level of the breech-chamber,

Aftel' i discharging thepiece the lever Eis depressed. l

or reached the position shown in Fig. 3, it stops for a certain time whtc the pin g is traveling downward through the vertical part of the slot It isduring this time that the extractor works, the adjustment ofthe parts being such that just at the time when the downward move men ofthe breech-block is suspended, thc hub o comes in contact with the point n and impart-s a positive movement to the extractor. The empty shell is thus forced out of the breech-chamber by a positive action, andwhen free from the. breech is ejected by the rapid movement ofthe armILcaused by the spring c',

through the opening at the rear of the breech\` case. At the moment when this is effected the breech-block is again set in motion and drawn down to its lowest point,the hammer in .the mean time being cocked. A fresh shell is then forced out of the magazine on the breechblock, and the lever E raised. The first effect of this is to raise the breech-block to bring the I cartridge carried by it into line with the breech-chamber. At this point it rests while the ping is moving up through the vertical portion of the slot f; but while this is taking place the hub o engages with the point n, and the arm H is driven positively frrward. By this means, and while the breech-block is stationary, the shell is forced h ome in the breechchamber. The breech-block then starts upward, closes the breech, and the lever E is locked. The piece is then in condition for a second discharge.

'Of the details of mechanism here shown which are common to other guns l have given no specific description, as their functions and mode of operation are well understood. I would state, however, that I use a movable cover, T, on the breech-case, or an equivalent device which is readily removed t0 facilitate access to the breech-mechanism.

The specic construction of the lever H, or the manner of its connection and operation by the hub o on the rock-shaft, I do not claim, except as it may enter into the combinations which I have herein set forth.

I do not limit myself to the exact construe tion of the parts herein described. Particularly is this the 'case with those devices orV parts which are ynot new in themselves. For example, the action may be considerably varied; or, in other words, the lever E, in lieu of forming a trigger-guard and being placed below the breech-case, may lie alongside the same. and so for many other obvious modifications.
